To change the position of the desktop wallpaper open the registry and navigate to [HKEY_CURRENT_USERControl Panel\Desktop]
and then either modify or create a new String values named Wallpaperoriginx and Wallpaperoriginy and set the value data to the horizontal and vertical offset. Now exit the registry, and restart your computer for the change to take effect. Note: The image is offset from the center of your desktop, so you can use positive and negative values.
